BACKGROUND OF THE devised, eyes to the joint portion of the outer wall, etc.
The present invention relates to a joint structure to which a ground bar is attached .

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, in order to ensure watertightness between end faces of a pair of adjacent outer wall panels 4, it is necessary to employ a conventional method.
This is performed by filling the caulking material 103 between the end faces. That is, the backup material 101 is sandwiched between the frames 4a of the outer wall panels 4, and the backup material 10
1 and a groove 102 formed between the end faces of the exterior material 4b of each outer wall panel 4 was filled with a caulking material 103. Reference numeral 5 denotes a fixture for fixing the frame 4a of each outer wall panel 4 to the horizontal member 106.

[0003]

However, in performing the filling operation of the caulking material 103, the exterior material 4b
Groove 1 so that unnecessary caulking material 103 does not adhere to
It was necessary to perform masking around 02, and the construction was complicated. Further, dust or the like may adhere to the surface of the caulking material 103 before the caulking material 103 is hardened, and may be contaminated. In addition, when a fire occurs in a neighboring house or the like, there is a risk that the fire may spread to the indoor part of the building through the end faces of the outer wall panel 4.

The purpose of this invention is to improve workability , disaster prevention and
An object of the present invention is to provide a joint structure having excellent waterproofness and good appearance.

And a secondary watertight material .

[0006]

According to the joint structure of the present invention, a pair of juxtaposed
The joints between the outer member of the panel, formed by the circumference of the refractory foam pasted the decorative sheet to the surface portion covering a rubber joint
By providing the rod, watertightness between the pair of panels can be ensured. Further, even if a fire occurs in a neighboring house or the like, the fire does not spread to the indoor part of the building through a pair of panels . Further, by exposing the decorative sheet to the outdoor side from between the pair of panels, it is possible to prevent adhesion of dust and the like. In addition, secondary watertightness is in contact with the back of the joint rod.
Since the material is interposed, the waterproofness between the exterior materials of the pair of panels is improved.
Even better.

BRIEF DESCRIPTION based on joint structure of a first embodiment of the invention in FIGS. As shown in FIG. 1, a joint rod 10 is obtained by covering the periphery of a refractory foam 1 with rubber 2 and affixing a decorative sheet 3 to a surface portion thereof. The refractory foam 1 is a long plate material mainly composed of a polyurethane resin composition comprising a polyol and a polyisocyanate, ammonium polyphosphate, a polyhydric alcohol, and an amine group-containing compound. Rubber 2 is EPP
It is made of M (ethylene / propylene / diene / methylene) and integrally forms the draining portion 2a. The decorative sheet 3 is made of a chlorosulfonated polyethylene resin and has a decorative finish on the surface.

At the time of construction, as shown in FIG. 2, one outer wall panel 4 is first placed on the lower floor, and a bolt 8a is fastened to a welding nut 8b provided inside the frame 4a. The outer wall panel 4 is fixed to the fixing bracket 5. Exterior material
The joint rod 10 is adhered to the upper end surface of the outer wall panel 4 in a state where the outdoor surface at the upper end of the outer wall 4b is covered with the drainer 2a. A secondary watertight material 6 made by sticking a butyl rubber adhesive sheet material 6b to one surface of a single-bubble or open-cell resin 6a is attached to a frame 4a of one outer wall panel 4 in contact with the rear portion 2b of the rubber 2. Adhere to the top of

Further, the outer dimensions of the secondary watertight material 6 are reduced to the outdoor side on the lower end surface of another outer wall panel 4.
Next, the watertight material 7 is bonded with a pressure-sensitive adhesive sheet material 7b made of butyl rubber. One outer wall panel 4 has another outer wall panel 4 on its upper end surface.
, The other outer wall panels 4 are arranged on the upper floor by compressing and deforming the secondary watertight members 6 and 7, and bolts 8a are fastened to welding nuts 8b provided inside the frame 4a to secure the other outer wall panels 4. The outer wall panel 4 is bonded to the fixing bracket 5.

As described above, the joint bars 10 are sandwiched between the end surfaces of the pair of outer wall panels 4 arranged on the upper and lower floors, so that
Water tightness between the end surfaces of the pair of outer wall panels 4 can be ensured, so that a conventional masking operation is unnecessary. Moreover, since the joint rods 10 are adhered to the outer wall panel 4 at the stage when the outer wall panel 4 is stood on a building or the like, it is not necessary to provide a scaffold or the like and perform mounting work at a high place, which facilitates construction. Also, even if a fire occurs in a neighboring house or the like, the fire does not spread to the indoor part of the building through the end faces of the outer wall panel 4, and thus the fire protection is excellent. Further, since the decorative sheet 3 is exposed from between the end faces of the outer wall panels 4, it is possible to prevent dust or the like from adhering, so that the appearance is good. Furthermore, eyes
Since the secondary watertight material 6 was interposed in contact with the rear part of the ground rod 10,
The waterproofness between the end faces of the pair of outer wall panels 4 is further improved.
You. Other configurations are the same as in the conventional example.

Next, a joint structure according to a second embodiment of the present invention will be described.
The structure will be described with reference to FIG. The joint rod 20 is for securing water tightness between the side ends of the pair of outer wall panels 4 arranged side by side in the horizontal direction.
2 and a decorative sheet 13 is attached to the surface. The rubber 12 has a hollow portion 12a on one side.
At the time of construction, the joint material 20 is sandwiched between the end faces of the pair of outer wall panels 4 by compressively deforming the secondary watertight material 9 and the hollow portion 12a. Reference numeral 11 denotes a butyl rubber adhesive sheet material. Other configurations and effects are the same as those of the first embodiment.

[0012]

[Effect of the invention] According to the joint structure of the invention, the joints are juxtaposed.
The joints between the outer package of a pair of panels, and the periphery of the refractory foam pasted the decorative sheet to the surface portion covering rubber
By providing the joint bar, water tightness between the pair of panels can be ensured. Therefore, the conventional masking work is not required, and the construction is easy. Also,
Even if a fire occurs in a neighboring house or the like, the fire does not spread to the indoor part of the building through a pair of panels , and is excellent in disaster prevention. In addition, since the adhesion of dust and the like can be prevented by exposing the decorative sheet to the outdoor side from between the pair of panels , the appearance is good. In addition, secondary to the back of the joint bar
Watertight material is interposed, so waterproof between the exterior materials of a pair of panels
The properties are further improved.
